Chesterfield · TR19 Grease
We clean the full commercial duct run - grease, dry and laundry ductwork, canopy to roof fan - for kitchens, offices and industrial sites across Chesterfield, and certify it to the TR19 Grease standard your insurer expects.
Chesterfield
Chesterfield rates around 950 food premises, and behind a large share sits an extract duct a canopy clean never reaches - plus the dry ductwork and air-handling that keep its offices and public buildings running.
Kitchens across Chesterfield work out of tight, mixed premises - Chatsworth Road, Knifesmithgate, Market Place - their extract snaking through concealed voids to roof-mounted fans. We take the whole run to the TR19 Grease standard, hood to fan, reaching the horizontal legs and vertical risers a canopy wipe never touches.
Kitchens are only half the work - we also strip the dry supply and extract ductwork of Chesterfield schools, offices and civic buildings, and the lint-choked dryer runs behind its hotels and care homes. It is the hardest-pressed kitchens - Chesterfield College, Chesterfield Royal Hospital, the SMH Group Stadium and the town hotels - that glaze their hidden ducting quickest, and that coating is the road a fire takes.
The standard
TR19 Grease is the benchmark Chesterfield insurers and fire risk assessors expect - measured across the whole extract run, not just the visible mouth of the canopy.
Grease is measured by thickness, and the standard sets the depth at which a system must be cleaned and re-tested. Around Chatsworth Road and Market Place, where the concealed runs thread through mixed roof voids, a canopy-and-filter wipe leaves the ductwork itself - the long hidden sections where grease accumulates and a fire travels - untouched. We access the full Chesterfield run through existing and newly fitted inspection hatches, clean to bare metal, record before-and-after grease-depth readings at set points, and issue a TR19 Grease certificate with a post-clean depth record.
By system
The fire risk. Fried-food extract coats duct walls in combustible grease; cleaned canopy to fan and certified to TR19 Grease.
Supply and general extract in offices and public buildings, carrying dust and debris that throttles airflow and loads the air-handling unit; cleaned to TR19.
The hidden one. Tumble-dryer ducting packs with lint - highly combustible - in Chesterfield hotels, care homes and gyms.
On the ground in Chesterfield
We are in Chesterfield's ductwork and plant every week. The proof is the jobs, not the stock photos.
A secondary school in Chesterfield had the washroom extract grilles matted with thick grey dust and paper-towel fibre, choking the ventilation. We unclipped the diffusers for a detailed sanitise and ran flexible rods through the galvanised ductwork, restoring positive extraction and clearing the stale humidity. It was scheduled into a half-term with the premises empty.
When it is due
Ductwork rarely warns you politely. In a busy Chesterfield kitchen these are the tells.
Smells pushing back into the dining room, a canopy that drips onto a Chatsworth Road cookline, extraction that no longer clears the steam, visible grease at the filter edges, or a Chesterfield insurer or fire risk assessment asking for a TR19 certificate you cannot produce. Cleaning frequency tracks use - a hard-frying Knifesmithgate kitchen needs it far more often than a daytime cafe - and your certificate states the interval, so the next clean is never a guess.
How it runs
Inspect the full Chesterfield run, find the access gaps in the concealed sections, agree scope and frequency.
Fit inspection hatches where the run is sealed - common in the older Market Place conversions - and protect the kitchen.
Canopy to roof fan, down to bare metal, with before-and-after grease-depth evidence.
TR19 Grease certificate, grease-depth record and next-due date for your Chesterfield fire logbook.
Why it matters
Three duties push every Chesterfield operator to keep ductwork clean, and they reinforce one another.
Fire safety law. Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person for a Chesterfield premises must assess and manage fire risk. A grease-laden duct is one of the most serious risks in any catering building, because a flare-up on a Chatsworth Road cookline can travel the ductwork and spread fire through concealed voids. The Health and Safety at Work etc. Act 1974 and the HSE reinforce the same duty of care.
Insurance. To a Chesterfield insurer a current TR19 Grease certificate is the proof the extract has been kept up. Let it lapse and a fire claim can be scaled back or declined outright - the kind of gap nobody wants to find with the kitchen already gutted.
Hygiene and environmental health. When Chesterfield Borough Council carries out a food hygiene inspection it judges the physical state of the premises, and ventilation is part of that. A grease-choked extract can pull down the rating an Environmental Health Officer gives, on top of the odour and the weakening airflow your staff put up with.
It is set by cooking hours under TR19 Grease - roughly every three months for heavy use of 12 to 16 hours a day, every six for moderate, every twelve for light. A hard-frying Chatsworth Road kitchen sits in a tighter band than a daytime Knifesmithgate cafe. We measure the grease load and confirm your interval.
Yes - from Chatsworth Road and Knifesmithgate kitchens to the offices, schools and industrial units across Chesterfield and the wider Derbyshire.
We fit compliant access panels where the ductwork has none, so every internal section can be reached, cleaned, inspected and certified - common in the older Market Place conversions where the run was boxed in with no hatches.
Yes. We clean the dry ductwork and air-handling in Chesterfield offices, schools and public buildings, and the lint-heavy laundry ducts in the Derbyshire hotels and care homes, alongside kitchen grease ducts.
Yes. We work overnight, early mornings and closing days for the Chatsworth Road and Knifesmithgate kitchens, and around shift patterns at commercial and production sites, at no extra charge for out-of-hours work.
The full run, canopy through the concealed horizontal and vertical ductwork to the roof fan - the hidden sections a canopy-only clean leaves loaded, which matters in the tight stock around Chatsworth Road and Market Place where the runs are long and awkward.
A dated TR19 certificate, before-and-after photographs of each section, and an access report for your fire logbook - the evidence a Chatsworth Road operator's insurer and fire risk assessor expect.
